some of the wires are in different positions on the loom between early and later 1.4 16v corsas. mainly the knock sensor system.

kool thats all i need to know thanks

from personal experience i would say yes, ive used a ecu on my 1.4 from a different 1.4, also at one point was using a 1.6 tigra ecu on my 1.4 corsa and was fine.

i know i need the chips etc but with the ecu from a later sport? fit mine which is and earlier sport (p reg)

as said if you change ecu for another one with built in imob you will need the chip from the key that matches that ECU, also pretty sure you need the lock barrel pickup aswell (i got both when i swapped mine)

if you find a mega early one it doesn't have the transponder system at all :thumbs:

i have a corsa sport 1.4 16v p reg, but my ecu doesnt have a removable eprom chip, but the later or earlier ones do can i just get an ecu from another 1.4 16v sport that has a removable eprom and fit it along with the transponder chips from the ignition and key? will this work?
